How to get an insanely expensive car for free cheat for Gran Turismo 5

In GT5 you get a car on your birthday, and the car you get is from the year you are born. So make a lot of PSN users and say they are born in 1967 and the date today(when you are using this cheat). after you have made the user, enter GT Life and the message will appear.

PS: You do not get a expensive car evrytime but mostly.PS: 1967 is the best year because almost all of the most expensive cars is made in that year.
